We could live several lifetimes and never exhaust the power of our minds.

Never underestimate the power of thought; it is the greatest path to discovery.

if there is any worry in your mind, and if at that moment the words 'My Lord' comes to your lips, then believe me your worry will be destroyed. If at that moment you remember that you are not without a Protector, you have (are with) a Protector, then how can fear remain? Fear comes only in the lives of those who are without any Protector.

Much more surprising things can happen to anyone who, when a disagreeable or discouraged thought comes into his mind, just has the sense to remember in time and push it out by putting in an agreeable, determinedly courageous one. Two things cannot be in one place.

The greater a man's talents, the greater his power to lead astray.

Staying angry gives the people who hurt us continued power over us.
